What is Sign Protocol (SIGN)?

Sign Protocol (SIGN) is an “omni-chain attestation protocol”. In simpler terms, it is a suite of tools that allows users and businesses to create attestations — secure statements that can prove something is true. These attestations can confirm anything from a person's credentials to the authenticity of a document. Once an attestation is created, anyone can check its validity at any time without needing to blindly trust the person who made it.

One important thing to understand is that Sign Protocol is not a blockchain. Instead, it uses blockchain technology when needed, but it works independently of any single blockchain. This makes it omni-chain, meaning it can operate across many different blockchain environments.

In its early stages, Sign Protocol already supports major ecosystems like Ethereum and other EVM blockchains, TON, and Solana. However, it is built to be flexible, so it can adapt to almost any blockchain or web environment in the future.

The goal of Sign Protocol is simple but powerful: make the internet a place where truth can be proven easily, securely, and without middlemen.

Who Created Sign Protocol (SIGN)?

Sign Protocol was founded in 2021 by Xin Yan, Potter Li, and Jack Xu. The team started with a project called EthSign, which focused on digital document signing. They later expanded their vision to create Sign Protocol, aiming to provide a broader solution for verifying information online.

What VCs Back Sign Protocol (SIGN)?

In March 2022, Sign Protocol raised $12 million in a seed funding round. Investors included well-known firms like Draper Associates, Sequoia Capital, and Mirana Ventures. Later, in January 2025, YZi Labs, affiliated with Binance Labs, invested an additional $16 million. This support has helped Sign Protocol grow and develop its technology.

How Sign Protocol (SIGN) Works

Sign Protocol operates by allowing users to create attestations—digital statements that confirm the truth of a claim. These attestations are structured using schemas, which define the format and rules for the information. Once created, an attestation is signed with a digital key, ensuring its authenticity.

1. Attestations

An attestation is simply a signed statement that proves something happened or is true. Think of it like a digital stamp of approval. In Sign Protocol, an attestation includes structured data — like facts, proof, or evidence — and a digital signature that makes it secure.

People or companies can create attestations for almost anything:

● A university could attest that a student graduated.

● A person could attest that they attended a concert.

● A business could attest that a product meets certain standards.

Once an attestation is made, it becomes verifiable forever — meaning anyone can check if it’s real by looking at the data and verifying the signature.

2. Schemas and Schema Registry

To keep things organized, Sign Protocol uses something called a schema. A schema is like a blueprint that describes how an attestation should be structured. It defines what data should be included, what format it should be in, and how it can be verified.

For example, a schema for a graduation certificate might include fields like:

● Student Name

● School Name

● Graduation Date

Sign Protocol also offers a Schema Registry, which is a big collection of these schemas. This makes it easy for users to reuse existing structures or create new ones that fit their needs. The Schema Registry also sets rules to keep attestations consistent and easy to understand across different systems.

3. On-Chain and Off-Chain Attestations

One of Sign Protocol’s strengths is that it works both on-chain and off-chain:

● On-chain means the attestation is stored on a blockchain like Ethereum or Solana. This is useful when you want the highest level of public security.

● Off-chain means the attestation is stored somewhere else on the web, like a database or server, but still carries all the cryptographic proof needed to verify it.

This flexibility means developers and businesses can choose the best storage method depending on what they need.

4. Portability and Multi-Chain Support

Sign Protocol is built to work across many different blockchains and systems. Right now, it supports Ethereum, EVM-compatible blockchains, TON, and Solana.

But because it isn’t tied to any one blockchain, it can easily be adapted to new environments as they emerge. This makes it a truly future-proof system.

5. Disputes and Revocations

What happens if someone makes a false attestation? Sign Protocol allows for disputes and revocations.

If new evidence shows an attestation was wrong or fake, another attestation can be created to revoke or correct it. This keeps the system honest without allowing simple tampering.
